What is a stent placement?
A stent is a wire mesh stainless steel tube that holds an artery open and keeps it from closing again. It becomes a permanent part of your artery.
Why is it necessary?
Fatty deposits can block blood flow through arteries and cause pain. A piece may break off, form a clot, and cause a heart attack or stroke. A stent opens the blockage and keeps it open, which allows blood to flow smoothly. Good blood flow reduces pain and risks of clots forming.
How is it done?
The doctor will insert a tiny, flexible plastic tube called a catheter through an artery in our groin, leg, or arm. A special dye is injected so blood flow through the arteries is visible on the TV monitors. The doctor moves a balloon catheter, and then a stent, to the site of the blockage. The balloon is inflated and stretched wide against the artery walls, which opens the blockage. Then the balloon is deflated and taken out, leaving the stent in place.
What should you expect?
The procedure may take place right after the arteriogram, which is used to find the blockage, or it may occur the next day.You may need to stay in the hospital two or three days.
